Clamav-daemon and freshclam keep starting at bootime

I have stopped and disabled the clamav-daemon and clamav-freshclam services. The following commands have been used to stop and disable them from running at bootime :

service clamav-daemon stop

service clamav-freshclam stop

update-rc.d -f clamav-daemon remove

update-rc.d -f clamav-freshclam remove

I can also check if they have been disabled with the sysv-rc-conf command.

The problem is that they keep start at bootime and I don't understand why. They must be referenced somewhere in other programs configurations. The only thing I could think of was amavis / postfix, but I have also disabled amavis.

Any ideas on this without actually uninstalling clam ?

Just checked the VPS again and apparently I'm having the same issue with bind9

Just noticed that I posted in the wrong section. Could a moderator please move it to the ISPconfig3 - Installation/Configuration section ?
